Contact lens rear vertex power verification lens

CC-2014 and CC-2014 Plus are calibration lens sets developed by Langshan Optics specifically for the contact lens industry. They are made of high-quality optical glass and have specially designed tooling brackets that can effectively protect the lenses and greatly improve operational comfort.

The back surface of the lenses in CC-2014 and CC-2014 Plus brackets is used as the reference (i.e. positive power is based on the plane, negative power is based on the concave surface), ensuring that they meet the industry standards for optometry and remain consistent with the unsupported state when in the measuring dish.

CC-2014 and CC-2014 Plus can provide a calibration certificate issued by the metrology institute in accordance with JJG 866-2008 "Verification Regulations for Top Power Standard Lenses" at the factory, along with other necessary parameters for conversion in solution, such as curvature radius, center thickness, effective focal length, etc.

CC-2014 and CC-2014 Plus are packaged in wooden boxes, with each lens labeled and labeled. The customized tilted lining provides excellent protection and enhances operational convenience.
